High temperature and high pressure power station gate valve, also known as special valve, the pipeline mainly used in the thermal power plant system, cut off or connect pipe medium. Applicable medium: water, steam and other corrosive medium. Power station valve compared with other valve products is characterized by high temperature and high pressure, the unique since the seal design, the higher the pressure, the more reliable seal. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products.

use

Installed on the water, steam pipeline as an opening and closing device.

The structure is briefly

1, using pressure self-tightening seal structure, flexible disc, on both ends of the pipe for welding.

2, the valve seat sealing surface using cobalt-based hard alloy plasma spray welding and become, wear resistant, good abrasion resistance.

Clapper sealing surfaces by hardening nitriding processing.

3, the valve stem surface corrosion resistance of the nitriding treatment, good resistance to corrosion and abrasion resistance.

4, opening and closing of the valve controlled by electric actuator, electric actuator, respectively, with special motor, reducer, torque control institution, the operating mechanism, hands, electric switching mechanism, in addition to the on-site operation and remote operation can be performed. According to user&＃39;s request matching yangzhou electric equipment plants introduced Siemens technology to produce 2 sa30 series, introduces the British ROTORK production of A series, Ricky, measurement and control equipment co., LTD. RA series electric head.

The advantage of structure:

High temperature and high pressure power station valve temperature 450-570 ℃, pressure PN1.6-70.0, nominal diameter 15 mm - 300 mm material: 1 cr5mo, 12 crmorv ZG12CrMoV is widely used in iron and steel, metallurgy, chemical industry and electric power, power plants and other facilities.

Technology advantage:

1, adopt the forging and casting technology options, bright and clean appearance, uniform organization, satisfies the requirement of high temperature and high pressure; Depending on the user needs all can provide a full range of forged steel gate valve;

2, special material matching, ensure high sealing surface hardness and hardness difference; Precision grinding, bright as a mirror, wear-resisting corrosion resistance, prolong service life;

3, the back seal design, effectively protect the packing, put an end to PaoMaoDiLou;

4, the intensity of high pressure water, high pressure gas intensity, nondestructive testing and other multi-channel detection, comprehensive control of pressure parts;

5, the valve stem by precision grinding and surface hardening treatment, scratch resistant corrosion resistance, effectively reduce the open-close torque, operation more easily;

6, the use of special corrosion packing structure design, the pressure of heat-resistant, non-corrosive, automatic lubrication, friction reducing opening and closing, avoid corrosion on the surface of the valve stem, and exempt from leakage;

7, two-way pressure seal design to meet the demanding requirements of all kinds of special conditions,

8, manual running-in strictly, guaranteed that the double side seal face alignment by more than 90%, for detecting level bubble factory sealed;

9 and unique Z60 series of ram elastic groove design, automatic compensation of processing error, to adapt to the working condition of high temperature, avoid killed; Z62Y series designed for double ram, the ram automatic error correction processing, always keep *** inosculation on sealing surface, especially making it easy for users to the site maintenance;

10, the bonnet from close seal design, the higher the pressure, the more reliable seal;
